HIRAM P. STEWARD, OF ELIZABETH, NEW JERSEY, ASSIGNOR TO THE SINGER MANUFACTURING COMPANY, A CORPORATION OF NEIV JERSEY.

SEWING-MACHINE BINDER.

SPECIFICATION forming part of Letters Patent No. 794,690, dated July 11, 1905.

Application filed March 11, 1905. Serial No. 249,523-

To (all whom it may concern.-

Be it known that I, HIRAM P. STEWARD, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Sewing-Machine Binders, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has for its object to provide a sewing-machine binder in which the channel for the binding-tape, while affording a free guideway through which the same may be drawn without material resistance, is adapted to yield freely for the passage of inequalities .7

in the tape due to cross-seams, &c.; also to adapt the attachment for the easier introduction of the tape into its receiving end than has been practicable in devices of this nature heretofore in use. These objects have been attained in the preferred form of the present improvement by the provision of a rigid D- shaped tube with a transversely-extending pin at the receiving end which is embraced by a loop formed at one extremity of a doubledover spring-plate of which the opposed members are projected through said tube toward the delivery end and suitably spaced from the parallel upper and lower walls of the same to provide yielding tapering channels for the edge portions of the binding-tape embracing the divergent tongues afforded by the members of the plate referred to.

' In the drawings annexed, Figure 1 is a perspective view of a sewing-machine throatplate to which is applied a binder embodying the present improvement. Fig. 2 is a vertical longitudinal section of the binder through the center of its tubular portion, and Fig. 3

a horizontal section of the same.

As represented herein, the throat-plate 1 is provided with the needle-hole 2 for the needle 3 and with the angular aperture 4 to receive the feed-dog 5. The binder is constructed with the usual base 6 with elongated slot? for the fastening-screw 8, whereby the same is secured upon the throat-plate, and is pro- Vided with the vertical edge-guiding flange 9,

12, extending partially across such tube, be- I tween the head 13 of which and the flange 9 is a loop 14, formed in the adjacent end of a spring-plate having the diverging tape-supporting members 15, extending to the delivery end of the tube and'terminating in the offset portions 16, lying flush with the workguiding groove 10 of the flange 9, recessed in the adjacent faces to receive them, thereby spacing said members from the parallel opposite walls of the tube member 11 to afford a narrow binding-channel.

The top of the receiving end of the tube member 11 is cut away forward of the transverse pin 12 for the easy introduction of the end of the binding-tape into the attachment, the tapering channel afforded by the springtongues 15 permitting the passage of the same to the delivery end without obstruction, while the resilient nature of such tongues readily permits the yielding of the inner walls of the channel to accommodate any unevenness in the binding-tape which would not be easily accommodated by the clearance provided in the normal thickness of the guiding-channel.

In the type of binder herein shown the binding-tape is drawn through the same transversely of the line of feed and bent over the inclined forward ends of the tongues 15, with its middle portion in contact with the guiding groove or notch 10, the edge of the material to be bound being inserted between such extremities of the tongues 15 and within the binding thus bent over the same; but it is evidently immaterial to the present invention whether the characteristic features of the latter be embodied in such type of binder or'one in which the tubular portion of the binder is disposed parallel with the line of feed, and it is also to be understood that the present improvement may be varied materially in its details of construction without departure from the spirit of the present invention.

While the yielding feature of the bindingguide as herein described is deemed of considerable importance in the performance of its described function, it is evident that the tapering form of the tape-guiding channel is of importance, as this permits of the easy introduction of the tape and obviates, to a large extent, the clogging to which binders having channels of uniform thickness are liable. The present construction is also specially advantageous in that the several parts are of extremely simple form and may be manufactured separately at small expense and subsequently assembled with ease, new parts being readily substituted for the old in case the effectiveness of the attachment becomes impaired by continued use or otherwise.

Having thus set forth the nature of the invention, what I claim herein is- 1. In a sewing-machine binder, the combination with the base member provided with a rigid D-shaped binding-tube, of a pair of spring-tongues extended through said binding-tube and having one extremity connected to said tube at its receiving end and the other extremity free to yield toward each other.

2. In a sewing-machine binder, the combination with a base member provided with a rigid D-shaped binding-tube, of a transverse pin arranged centrally of said tube at its receiving end, and a pair of supporting-plates connected with said pin at one extremity and diverging outwardly therefrom toward the delivery end of said tube from the opposite walls of which they are respectively spaced to form binding-channels.

3. In a sewing-machine binder, the combination with a base member provided with a rigid D-shaped binding-tube, of a transverse pin arranged centrally of said tube at its receiving end and a pair of supporting springplates connected with said pin at one extremity and diverging outwardly therefrom to the delivery end of said tube from the opposite walls of which they are respectively spaced to form binding-channels.

4. In a sewing-machine binder, the combination with a base member provided with a rigid D-shaped binding-tube having at its delivery end a transverse work-guiding groove, of a transverse pin arranged centrally of said tube at its receiving end, and a pair of supporting spring-plates connected with said pin at one extremity and diverging outwardly therefrom toward the delivery end of said tube and having laterally-offset portions resting upon the respective sides of said work-guiding groove.

5. In a sewing-machine binder, the combination with a rigid D-shaped binding-tube, of a transverse pin arranged centrally of said tube at its receiving end, and a pair of supporting spring-plates formed integrally and looped around said pin at one extremity and diverging outwardly from the latter to the delivery end of said tube from the opposite walls of which they are respectively spaced to form binding-channels.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.

I HIRAM P. STEWARD.
